I got me a solar water heater at the fish farm. Works pretty darn good too.
Fairly simple, I use it to warm up a large fish tank that is protected from the wind and cold by a plastic wrapping around the fish house.
The heater consists of a small water pump, 100' of 1/2" black poly hose and the silver painted, tin roof of the fish house.
I pump fish tank water through the hose and the sun on the roof warms the water from 4 to as much as 15 degrees as it passes through and back to the fish tank. Alternatively I hook the heater hose to the new water source and heat the source water as it enters the tank.
When water temps outside were in the high forties, I kept the inside temp around sixty nost of the time. Warm enough to keep feeding the fish in the tank.
